Rose plant

ABSTRACT

1. A new and distinct variety of rose plant of the hybrid tea class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of strong, extremely thorny stems carrying a great many thorns, flowers or large, many petaled and excellent substance, with vivid red and yellow bi-coloring.

The present invention relates to a new and distinct variety of rose plant of the hybrid tea class, which was originated by me by crossing the rose variety known as "Sunrise-Sunset" (U.S. Plant Pat. No. 3,244) which I have chosen to identify in my breeding records as No. 6651-12 with a rose variety known as "Peace" (U.S. Plant Pat. No. 591), the seedling No. 6651-12 being the seed parent and the pollen parent being the variety "Peace". As the result of this breeding, I have produced a new and improved rose variety distinguished from its parents, as well as from all other rose varieties of which I am aware, evidenced by the following unique combination of principal characteristics which are outstanding in the new variety:

1. The stems are strong and extremely thorny;

2. Flowers are large and many petaled, and have excellent substance; and

3. A distinctive flower of vivid red and yellow bi-coloring distinguishing this new seedling particularly.

Comparing my new variety with the seed parent, it is noted that the seed parent variety lacks the prolific blooming habit of my new variety; and the petal substance of the parent plant is not as good as in the seedling, whereas the flowers of the new variety are a true bi-color with cherry red inside petals and straw yellow at the base.

In comparison with the pollen parent ("Peace"), the new variety is a substantially taller growing plant than the pollen parent, and the flowers are not as large although many petaled, having fewer petals than ("Peace") being more of an overall light yellow with pink edgings whereas the instant seedling is a definite combination of red on the inside petals and yellow on the outside petals, making it a true bi-color and not a blend of shades.

Asexual reproduction of my new variety by budding, performed by me at Chino, Cal., demonstrates that the aforementioned characteristics and depth and distinction come true to form, are established, and are transmitted through succeeding propagations.

The accompanying drawing shows typical specimens of the vegetative growth and flowers of my new variety in different stages of development, and as depicted in color as nearly true as is reasonably possible to make the same in a color illustration of this character.

There is set forth in the following, a detailed description of my new variety, the color terminology being in accordance with Munsell's Color Cascade, published by Munsell Color Company, Inc., of Baltimore, Md., except where general color terms of ordinary dictionary significance are obvious:

This description of a newly opened flower was made from a rose grown outdoors in the month of September at Ontario, Calif.:

Color.--Outer Petal: Outside surface: Bright Yellow 25-5 bottom, fading quickly to a 29-2 blending into Fleshtone 33-2 half way up changing to a Pinkish Red 39-6. Inside surface: Buttery Yellow 27-5, abruptly changing to Cherry Red 40-10, 1/4 inch from bottom with occasional white streaks running the length of the petal. Intermediate Petal: Outside surface: Medium Yellow 27-3 at the base blending slowly upward into Fleshtone 31-2 with border of petal being Salmon Pink 38-6. Inside surface: Medium Yellow 27-5 blending sharply 1/4 inch from bottom into Orange Red 38-9. Inner Petal: Outside surface: Medium Yellow 27-5 blending upward to a Lighter Yellow 27-3, gradually changing to a Pink-Red 39-6 near the top. Inside surface: Medium Yellow 27-5 changing sharply 1/4 inch from bottom into Orange-Red 38-9.

The following description is of a rose that was open for three days outdoors during the month of September at Ontario, California.
